High-cleanness multilayer chip scraping device

Abstract

The invention discloses a high-cleanness multilayer chip scraping device which comprises a sliding saddle, a ram and a sliding saddle cover, wherein the ram is sleeved in the sliding saddle and extends out of the sliding saddle; the sliding saddle cover is of a hollow funnel shape of which two ends are opened; one opened end of the sliding saddle cover is fixedly arranged on one end face of the sliding saddle; the other opened end of the sliding saddle cover is sleeved on the ram; a chip scraping piece sleeved on the ram is fixedly arranged on the opened outer end face of the sliding saddle cover, which is sleeved on the ram; a chip scraping piece sleeved on the ram is fixedly arranged on the ram extending end face of the sliding saddle; a concentric-circle-shaped rinse tank sleeved on the ram is arranged in a cavity formed by the sliding saddle cover and the end face of the sliding saddle; and the end face of the concentric-circle-shaped rinse tank is fixedly arranged on the sliding saddle cover. According to the high-cleanness multilayer chip scraping device with the structure, iron chippings can be completely stopped from entering the interior of the ram and the cleanness of a moving guide rail surface of the ram can be kept; the surface of the ram can be cleaned without being detached in the operation process of a machine tool; and the processing requirements of high speed and high precision can be met. Meanwhile, the filtered cleaning liquid can be recycled and has the functions of energy saving and environment friendliness.

Description

technical field [0001] The invention relates to a sliding saddle device in a gantry machine tool, in particular to a high-clean multi-layer scraping device on the sliding saddle. Background technique [0002] With the continuous utilization of gantry compound machining centers, the multi-station processing of large parts has been realized, and the processing accuracy is high. One of the key factors affecting the accuracy of gantry compound machining centers is the ram, but the traditional ram directly adopts an external single The one-layer scraping sheet prevents iron filings from entering the machine tool. During the use of the machine tool, a large amount of iron filings remain on the ram. The single-layer scraping sheet can only remove part of the iron filings, and some fine iron filings will still enter the machine tool. , For example, the rail surface connecting the saddle and the ram, the iron filings adhered to the rail surface during the movement of the ram in the s...

[0002] With the continuous utilization of gantry compound machining centers, the multi-station processing of large parts has been realized, and the processing accuracy is high. One of the key factors affecting the accuracy of gantry compound machining centers is the ram, but the traditional ram directly adopts an external single The one-layer scraping sheet prevents iron filings from entering the machine tool. During the use of the machine tool, a large amount of iron filings remain on the ram. The single-layer scraping sheet can only remove part of the iron filings, and some fine iron filings will still enter the machine tool. , such as the guide rail surface where the saddle is connected to the ram, the iron filings adhering to the guide rail surface during the movement of the ram in the saddle can easily scratch the guide rail surface, greatly reducing the service life of the machine tool

At the same time, the iron filings entering the machine tool can easily cause unstable machining accuracy, and it is difficult to improve the machining accuracy and surface quality of the product.
